摘　　要：工程建设与人们日常生活息息相关,边坡不稳定或滑塌会威胁人类生命财产安全。在早期的工程建设中,由于地质构造情况、地下水位情况、夹层滑动面土体夹层等不良地质因素影响,边坡稳定性不足。针对该现象,文章通过对山西离石地区某高速公路边坡进行稳定性分析计算,对不同工况下的边坡稳定性进行评价,并基于饱和状态下的边坡处于欠稳定状态的分析结果,进行抗滑桩设计研究,通过数值计算对桩位、桩长、桩径、桩间距进行优化设计,以期得到最佳的抗滑效果,为抗滑桩设计提供理论依据。Engineering construction is closely related to people's daily life.Slope instability or collapse will threaten the safety of human life and property.In the early engineering construction,the slope stability was insufficient due to adverse geological factors such as geological structure,groundwater level,soil interlayer of interlayer sliding surface.In view of this phenomenon,this paper analyzes and calculates the stability of an expressway slope in Lishi area of Shanxi Province to evaluate the slope stability under different working conditions,and studies the design of antislide piles based on the analysis results that the slope under saturated state is in an unstable state.The pile position,pile length,pile diameter and pile spacing are optimized by numerical calculation,in order to obtain the best anti-slide effect and provide theoretical basis for the design of antislide piles.
